the borg in the beginning and the borg (including boss) at the end teleport to the console room in kage. please check the coding for this.
if you want to beat kage, you must be very patient. no chance at getting the op. when you get to the boss room, leave one person there and the rest go to the console room (the room where the person disables the shields for the 6 things that need to be destroyed to release the imrs.)
